    Thanks, everyone! I don't know when the next time will be, but I feel better prepared for it. ~Dan

    Easier way to get arbor into new mainspring?

    John, I searched around using those terms (transmission snap ring pliers) and got similar results to what I found before. It still isn't clear to me exactly what yours might look like. Would you be able to post a picture of your tool or link to similar? I did find these 9", angle tips ones...

    Easier way to get arbor into new mainspring?

    John, thanks for the suggestion. Do you go straight to the innermost coil with that technique and just try to gently press outward against the walls? Do you go around the whole coil bit by bit? One thing I tried to do with the pliers was grab the wall of a coil and try to rotate backward (as...

    How would you bush this removable bridge?

    Yeah, I saw that the second wheel (just down and to the left of the bridge) was a bit sloppy too. I wasn't sure if it was enough yet to warrant rebushing. ~Dan

    How would you bush this removable bridge?

    Thanks, Bruce. And, just to be clear, because it suddenly occurred to me I might not have been, I meant to take the movement apart and leave the bridge attached to the plate to bush or just bush the small bridge on its own. Thought it might be easier as far as work holding to leave it...

    Easier way to get arbor into new mainspring?

    I finally sat down today to get the replacement mainspring I sought help finding (https://mb.nawcc.org/threads/help-finding-modern-replacement-hole-end-mainspring-for-old-german-clock.174540/) into the cleaned barrel. Actually, I decided to do both the broken one and the strike one, which was...

    How would you bush this removable bridge?

    Finally finished cleaning, replacing the springs, and reassembling an old German time and strike for my parents. I was playing around the with trains and, unfortunately, saw this on a removable bridge (cock?) that the star wheel pivot rides in: Both of my parents' German wall clocks have...

    How does a crutch pushing on the side of a pendulum work? Sattler Mechanica M1

    Much to my delight, I've already heard from from them. My question was similar to what I posted above: how can the escapement mechanism provide an impulse to both swings of the pendulum or does it only impulse it for half of its period? Well, there you go. Mystery solved. I am surprised no...

    Crutch Adjustment - is this too out of level to attempt it?

    Lynsey, I'm looking at the pictures you posted in your original Gilbert thread (https://mb.nawcc.org/threads/how-to-split-this-gilbert.167159/) and these here. I think, maybe, you're missing a washer between the 3 lobed spring and the taper pin through the arbor? Hard to tell because of the...

    Solved Badische Clock Movement Keeps Stopping

    You can use the same oils you would use in a modern clock movement, but even that is a subject of much debate! :p More importantly, you'll want to clean the movement before re-oiling it. Just putting more oil on a dirty movement is a recipe for wearing out your clock faster. I've personally...

    Crutch Adjustment - is this too out of level to attempt it?

    If you remove the escape wheel, then, when you go to turn the minute hand, the whole train is going to move rather than the "clutch" slipping. So, the 3-lobed spring doesn't come into play with the escape wheel removed. (Well, that's what I think it would do in my head. I've never actually...

    How does a crutch pushing on the side of a pendulum work? Sattler Mechanica M1

    Well, just sent them a note on their Mechanica specific website (Uhrenbausatz | MECHANICA - Ihr persönliches Stück Zeitgeschichte). Hope to hear back from them. I really don't think the crutch pin is restrained in any way. At least, not in any way that the manual demonstrates. Kind of...

    How does a crutch pushing on the side of a pendulum work? Sattler Mechanica M1

    Thanks, Bruce. Before posting, I had already read that whole manual top to bottom and, while it has some fantastic information about adjusting the pallets for drop and lock and how a clock operates, it doesn't address this question. That manual is where I took the image from above. The beat...

    How does a crutch pushing on the side of a pendulum work? Sattler Mechanica M1

    One clock I've looked at and debated purchasing for years is the Sattler Mechanica M1 clock kit. One aspect of that movement that has puzzled me is how the crutch pushing on the beat adjuster on the left side of the pendulum could provide an impulse for both directions of swing. I've attached...

    About to embark on a Hermle GF simply stopped

    Lynsey, I was in the same state you were in before attempting to service my parent's 100+ year old German grandfather clock. I'm not sure what your level of experience with various movements is, but one thing that helped me to gain the confidence was fully documenting and understanding exactly...

    Help Help finding modern replacement hole end mainspring for old German clock

    Thanks, Allan! I stumbled across that same spring last night and thought it looked like a candidate. I'll give it a go. Still wondering if someone has an explanation about why the "Estimated Mainspring Thickness and Length" calculator is so far off. Recommending a spring that is nearly 3x...

    Help Help finding modern replacement hole end mainspring for old German clock

    Thanks, Shutterbug. I'm hoping not to have to do that as I don't have all the tooling I would need for it, but I will if all else fails. I was attempting to use the "Estimate Mainspring Thickness and Length Calculator" and getting some really weird numbers...

    Help Help finding modern replacement hole end mainspring for old German clock

    Just talking to myself here, but hoping the additional information will help people make me a suggestion. I found a better way to measure the spring (flat on bench and slowly wrap thread around the coils) and my initial length estimate was pretty off. My actual length was probably closer to...

    Help Help finding modern replacement hole end mainspring for old German clock

    More information: Barrel Diameter: 40.53 mm Arbor Diameter: 12.02mm With the thickness I measured on the old spring, the calculated thickness (by the formula .3927(D*D - d*d)/T) would be 59.4". My length measurement was as best as I good get. Could be closer to 60" all said and told...
